Chirp walked into Shark Tank Season 12 with a $45 million valuation for what looked like a simple back-pain wheel. The Sharks were visibly skeptical. Years later, the company has reported over $85 million in lifetime sales. That gap between early doubt and later growth is exactly why this episode still gets searched regularly.
This article covers who founded Chirp, what the Shark Tank pitch looked like, whether a deal was made, and how the company grew after the show — including the most recent revenue figures and new products.
What Chirp Is and What Problem It Solves
Chirp was founded by Tate Stock. The flagship product is the Chirp Wheel, a circular device you place along your spine while lying on the floor. As you roll back and forth, it applies pressure to the muscles around the spine and helps stretch out tension.
Think of it less like a piece of gym equipment and more like a portable self-massage tool for your back. You don’t need a therapist or a fancy machine — just the wheel and the floor.
The brand sits in the consumer wellness and pain-relief space. It started as a low-cost, almost DIY-style product before growing into a broader recovery brand. According to a Business Insider profile of the founder, the origin story is a straightforward one: a simple idea that solved a common problem cheaply, then scaled from there.
One important clarification: Chirp the back-pain brand is completely separate from Chirps, the insect-snack company that also appeared on Shark Tank. They are different companies with different products.
The Shark Tank Pitch — Season 12, Episode 3
Chirp appeared on Season 12, Episode 3, which aired in October 2020. Tate Stock pitched the Chirp Wheel as a back-pain and mobility solution, positioning it as something millions of people with everyday back tension could use at home.
The part that got people talking was the valuation. Chirp entered the Tank with a valuation of approximately $45 million. For a single-product wellness brand at the time, that number raised eyebrows. The Sharks reacted with clear skepticism, and that tension is a big reason the episode still gets replayed and searched.
Lori Greiner was involved in the pitch and showed interest in the product. Her involvement is part of why many viewers search for this episode specifically — Lori has a track record with consumer wellness products, so her attention to Chirp carried weight.
The pitch itself was built around a clear consumer pain point: back pain is extremely common, and most solutions either cost a lot or require going somewhere. The Chirp Wheel was inexpensive and worked at home. That was the core of the pitch.
Did Chirp Get a Deal on Shark Tank?
This is the question most people are searching for, so here it is directly: Lori Greiner offered a deal during the episode, and the on-air pitch ended with her involvement. However, it is worth knowing that Shark Tank deals shown on television do not always close after filming. Due diligence happens after the cameras stop, and terms can change or deals can fall through entirely.
Reliable episode recaps from sources like SharkTankBlog support that a deal was offered, but the exact final terms should be treated with some caution since post-filming outcomes are not always publicly confirmed in detail.
What is not in doubt is this: the Shark Tank appearance gave Chirp massive national exposure. Regardless of what happened with the deal specifics, being on national television in front of millions of viewers moved product. That exposure alone was significant for a direct-to-consumer brand.
Lori Greiner’s interest matters as context, but it would be a mistake to credit her involvement as the sole reason for the company’s growth. The numbers suggest Chirp built on that momentum over several years through its own sales and product work.
How Chirp Grew After Shark Tank
After the October 2020 appearance, Chirp kept selling and kept growing. Here is a clear timeline of what the reported numbers look like:
- Early post-show period: Annual revenue was reported at approximately $5 million. This reflects the period shortly after the episode aired and the initial sales boost from the national exposure.
- Mid-2024 update: SharkTankBlog reported annual revenue of $6.9 million and over $85 million in lifetime sales as of July 2024.
- Business Insider profile: A separate piece described the company as having grown into a $250 million sales business. This figure refers to cumulative sales, not current company valuation, and comes from a different reporting period — so it is not directly comparable to the annual figures above.
Different sources report different numbers because they were written at different times. The key takeaway is the direction: the numbers moved consistently upward over the years following the show.
New Products and Brand Expansion
Chirp did not stay a one-product company. In April 2024, the brand launched Chirp RPM, described as a hybrid massage-related recovery product. This is consistent with a broader move to position Chirp not just as a back-wheel brand, but as a full recovery and mobility company.
This kind of product expansion is exactly how many successful Shark Tank brands scale. They build credibility with a single strong product, grow an audience of buyers, and then offer that audience additional solutions in the same category. Chirp followed that same path.
Was the $45 Million Valuation Justified?
At the time of the pitch, the $45 million valuation felt aggressive to the Sharks and to viewers. For a product that was, at its core, a wheel you roll on your back, that number was hard to accept.
Looking back at the growth figures, the valuation argument looks different. A company that reaches $85 million in lifetime sales and continues expanding its product line has clearly built something real. Whether the valuation was precisely right in 2020 is debatable, but the growth trajectory suggests Tate Stock had a longer-term view of what Chirp could become.
That is a useful pattern to notice: early Shark Tank valuations that seem inflated sometimes reflect a founder’s vision of where the business is going, not just where it currently sits. Chirp appears to be an example of that.
Where Chirp Stands Now
As of the most recent available reporting, Chirp is still active and operating. Multiple update sources confirm the company is running, selling products, and expanding its line. The brand has moved well past the single-product stage and continues to market through direct-to-consumer channels.
For anyone who follows Shark Tank updates as a way to understand how consumer brands grow, Chirp is a useful case study. It started with a low-cost product targeting a universal problem, gained national attention from a single television appearance, and then used that momentum to build a multi-product recovery brand with tens of millions in cumulative sales.

Final Takeaway
Chirp is not a company that faded after its Shark Tank moment. The pitch was controversial because of the valuation, the deal involved Lori Greiner’s interest, and the post-show growth turned out to be substantial — over $85 million in lifetime sales, a newer product launch in 2024, and continued operations as of the latest reporting.
The short version: what looked like an overvalued gadget pitch in 2020 became a growing recovery brand with real revenue. That is the Chirp update.
